Stepper motors, from standard to precision.
Standard, high-precision, closed-loop, hollow-shaft, geared and lead-screw stepper motors — nine families from one factory.
Nine product families.
Standard Stepper Motor
2-phase NEMA frames, economical and widely used.
High-Precision Stepper Motor
0.9° step angle for finer positioning.
Closed-Loop Stepper Motor
Encoder feedback prevents step loss.
Hollow-Shaft Stepper Motor
Hollow shaft for wiring or piping through.
Geared Stepper Motor
Integrated planetary gearbox for high torque.
High-Precision Geared Stepper Motor
Low-backlash precision reduction.
External-Drive Lead Screw Stepper Motor
External lead screw drive for linear motion.
Through Lead Screw Stepper Motor
Through-type lead screw for long travel.
Fixed-Shaft Lead Screw Stepper Motor
Fixed-shaft lead screw, compact and rigid.
Fixed-Shaft Electric Cylinder
Integrated motor and leadscrew in a cylinder housing for linear push-pull motion.
Integrated Drive Closed-Loop Stepper Motor
Motor with built-in driver and encoder, ready to connect.
Holding torque at rated current.
2-phase ratings; 3-phase and closed-loop ratings available on request.
